Privacy Policy – Follow-up Writer

Last updated: November 5, 2026

1. Introduction

Follow-up Writer is a Chrome extension that helps users create professional follow-up messages using built-in templates or optional AI-powered generation.

This Privacy Policy explains what information the extension handles and how that information is used.

2. Information We Handle

Depending on how you use the extension, the following information may be processed:

Client names and sender names entered by users.
Email conversations and message text pasted into the extension.
Project or reference details entered by users.
Anthropic API keys voluntarily provided by users.

3. How Information Is Used

Information is used only to provide the extension’s follow-up message generation functionality.

Template Mode

When no Anthropic API key is configured, Follow-up Writer uses built-in templates.

In this mode, the extension does not send pasted email conversations to Anthropic.

AI Mode

When a user provides an Anthropic API key and chooses to generate an AI-powered message:

The email conversation and relevant form fields are sent to Anthropic’s API.
The API key is sent to Anthropic in the authentication header.
Anthropic processes the request and returns generated text.
The generated message is displayed in the extension for the user to review and edit.

Anthropic’s processing is subject to its own privacy policy and applicable terms.

4. Local Storage

Follow-up Writer uses Chrome’s local extension storage to retain:

The user’s optional Anthropic API key.
The user’s sender name.

These settings are stored locally in the user’s browser.

Users can remove their saved API key through the extension’s Settings panel.

The extension does not intentionally save pasted email conversations or generated messages in persistent storage.

5. Third-Party Services

Follow-up Writer uses the Anthropic API only when users choose AI-powered generation.

The extension does not operate its own backend server for processing user conversations.

Anthropic may process information according to its applicable privacy policy and API terms.

Please review Anthropic’s policies at:

https://www.anthropic.com/privacy

We do not sell users’ personal information.

Information is transmitted to Anthropic when required to provide the AI generation feature requested by the user.

We do not use the information handled by the extension for advertising, profiling, creditworthiness assessments, or unrelated purposes.

7. Data Retention and Deletion

The extension does not intentionally retain pasted conversations or generated messages after the popup session ends.

The API key and sender name remain in Chrome local storage until the user removes them or clears the extension’s stored data.

Users can remove their API key using the Remove key option in Settings.

Information transmitted to Anthropic is subject to Anthropic’s applicable data retention and processing policies.

8. Security

The extension stores the user’s optional API key in Chrome local extension storage and uses HTTPS when communicating with Anthropic’s API.

Users should protect their API keys and avoid sharing them with others.

Local browser storage should not be considered equivalent to secure server-side secret storage.

9. Children’s Privacy

Follow-up Writer is designed for general professional use and is not specifically directed at children.

10. Changes to This Policy

This Privacy Policy may be updated when the extension’s functionality or data practices change.

Any updated policy will be published at the same public URL.
